familiar Gates Lesson Objectives: In admittance to AND, OR, and not render, an other(prenominal) logic render like NAND and NOR argon also used in the design of digital circuits. The non circuit inverts the logic sensory faculty impression of a double star signal. The small circle ( cardhouse) at the production of the bright imageisation of a NOT door is officially called a negation indicator and designates the rational co-occurrence. The objectives of this lesson are to learn nearly: 1. popular proposition entrys - NAND and NOR. 2. How to implement NOT, AND, and OR penetration apply NAND supply only. 3. How to implement NOT, AND, and OR introduction exploitation NOR admissions only. 4. combining weight penetrations. 5. Two-level digital circuit implementations using universal gates only. 6. Two-level digital circuit implementations using other gates. NAND Gate: The NAND gate represents the balance of the AND act. Its name is an contraction of NOT AND. The graphic sign for the NAND gate consists of an AND emblem with a bubble on the outfit, denoting that a full concomitant operation is performed on the output of the AND gate. The truth hold oer and the graphic symbol of NAND gate is shown in the figure. The truth elude understandably shows that the NAND operation is the complement of the AND. NOR Gate: The NOR gate represents the complement of the OR operation. Its name is an abbreviation of NOT OR.

The graphic symbol for the NOR gate consists of an OR symbol with a bubble on the output, denoting that a complement operation is performed on the output of the OR gate. The truth table and the graphic symbol of NOR gate is shown in the figure. The truth table clearly shows that the NOR operation is the complement of the OR. Universal Gates: A universal gate is a gate which can implement every Boolean function without neediness to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is profitable since NAND and NOR gates are thrifty and easier to fabricate and are the underlying gates used in all IC digital logic families. In fact, an AND...If you neediness to maturate a full essay, holy order it on our website: Ordercustompaper.com
